Have to add my graitude,
kelly, it's thanks to you that I fell over the edge and not only went for the deal on the iMac but also installed Panther!
Still sorting through the networking, but I now can 'see' all computers from all of them. Suspect I'll have to place both printers on the new iMac, but will first try just putting the USB hub on it.
It's one sweet 'puter! Even see envy in my wife's eyes! She has some fused vertebra in her upper neck and thinks the adjustable screen is super, even if it was up on her desk! Better keep an eye out for that thing moving!
Maybe I should use the Kennsington lock thing!
